On Competition in Linear Persuasion Games
We study competition in persuasion with multiple senders in linear Bayesian persuasion games, where each sender's payoff depend only on the receiver's posterior expectation about a uni-dimensional state. Our main result provides a partial geometric characterization for equilibrium outcomes that are minimally informative. Building on this, we establish the sufficient and necessary condition for senders' competition to induce full information disclosure in all equilibria. We apply this condition to a game in which multiple senders compete in persuading a privately informed receiver to take a binary action. There, we show that a strong conflict of interests between senders is neither sufficient nor necessary to robustly — i.e., independently of the distributions of the state and the receiver's private type — induce full disclosure as the unique equilibrium outcome. We provide economically meaningful sufficient conditions for such robust full disclosure. Finally, we derive sufficient conditions that ensure a receiver to be strictly better off by exploiting senders' competition instead of consulting any single sender.

Towards Robust and Efficient Large-Scale Stochastic Optimization
The rapid advancements in machine learning have been driven by increasingly large datasets and growing computational power. Developing optimization algorithms that scale effectively with data size and the number of computing machines is critical but fraught with challenges, including computational bottlenecks and communication overhead. Additionally, large-scale stochastic optimization processes are inherently vulnerable to adversaries, such as corrupted training samples or compromised machines, which can significantly degrade model performance without robust safeguards. In this talk, I will delve into the dual challenges of efficiency and robustness in large-scale machine learning problems and present our recent work in addressing these issues, including novel approaches to scalable and resilient optimization.

A story of fire and water: cryptocurrency mining, power choice, and Environmental cost
We investigate the environmental impacts of cryptocurrency in China. We find a robust pattern of seasonal migration of Bitcoin mining activities that aligns with the country's monsoon seasons. Bitcoin mining requires a significant amount of electricity. Miners typically operate in cities with substantial hydroelectric power resources to take advantage of lower electricity price. However, during the dry season, when water scarcity increases electricity prices in these areas, miners relocate to cities with more coal-powered electricity supplies. This shift to coal-powered electricity for Bitcoin mining results in a notable increase in SO2 emissions, contributing to a 15% rise in annual SO2 emissions in China. Our study highlights the significant and adverse environmental consequences of cryptocurrency mining activities.

Benefit from Your Competitors: Franchise Service and Online Competition
Franchising organizations were prevalent for uniform offline stores, but nowadays they face severe challenges from third-party online competitors. While the literature mainly consists of studies that focus on within-franchise relationships and the encroachment of an individual franchisor's company-owned stores, our paper introduces online competition and demonstrates how it changes these franchise relationships. We model the pricing game between a franchisor, who recruits a franchisee, and its online competitor, who has not yet sold sits product through any offline channel. The franchisee's costly service leads to the (further) differentiation between two brands and more dispersed consumers' evaluations of the franchised product. We show that the differentiation through consumers' evaluations per se is not sufficient to induce the franchisee's costly service provision. However, online competition can overturn this in that the franchisee will voluntarily provide costly service to drag online sellers out from the fierce price competition. In addition, this service incentive is enhanced if the product has some brand characteristics or nature that makes it difficult for consumers to discover their preferences through the merely display of products. We further show that the franchisor and the franchisee can both benefit from the existence of the online competitor. The presence of inter-brand competition can mitigate the intra-brand competition, and this is made possible only when service provision is at the franchisee's discretion. Our findings suggest that online competition makes the franchise relationship more interconnected in that the franchisee is voluntarily provide costly services to (directly) benefit the franchisor.

Sequential decision making: trade-off between optimality and safety
This talk explores the integration of safety into optimality in sequential decision-making for online experimentation, specifically within a stochastic multi-armed bandit setting. Previous work mostly focuses on “optimality” of sequential decisions -- achieving efficiency by minimizing regret expectation. However, maintaining “safety” -- controlling the regret tail risk, is essential in critical applications. This work provides a characterization of the trade-off between optimality and safety.

从乡愁到乡酬:老乡关系对于销售绩效的影响
技术的发展已经改变了销售人员在商业与消费者环境中与个人消费者的互动方式,通过在线平台促进远程互动。在与一家建筑行业的在线培训机构合作的过程中,我们发现销售人员被随机分配给客户,并通过即时通讯应用程序(微信)进行联系,这项研究表明,即使没有面对面的接触,双方共享同一家乡也能显著提高销售绩效。来自同一家乡的客户和销售人员对的转化率比其他人高出24%。我们将这种增长归因于消费者方面的反应提高,因为我们的分析表明,共享同一家乡会引导消费者产生更积极的情绪并更快地回复。与此同时,销售人员方面并未观察到类似的模式。为了理解这些客户的反应,我们提出了两种可能的解释,即家乡对的文化接近性和偶然相似性,并为这两者提供了暗示性的证据。我们的发现为优化商业与消费者环境中的销售队伍管理提供了宝贵的管理洞察。

The Interplay between Innovation and Marketing: Evidence from the Pharmaceutical Industry
This paper examines the long-standing question about the interplay between firms’ innovation and marketing decisions. We develop new perspectives that emphasize the relationships of different marketing activities to innovation and the dynamics of their relationships. Exploiting detailed data on firm-level expenditures and innovation outcomes (patents and new drug applications) and a quasi-experimental policy setting in China during 2009–2018, we examine how firms respond to policy-induced innovation incentives in China’s pharmaceutical industry. We find that as regional innovation policy reforms in China spurred pharmaceutical R&D investments, firms significantly reduced non-advertising marketing expenditure. However, firms raised future advertising expenditures when past R&D input generated innovation outputs. The advertising responses are particularly strong for firms introducing new prescription drugs or those with products in therapeutic classes with shorter R&D cycles. Our results suggest that while firm innovation substitutes non-ad marketing activities, advertising and innovation are dynamic complements. Our study also underscores the importance of understanding the (unintended) impact of innovation policies on marketing activities.

Product Design Minimalism and Consumer Behavior
Product design minimalism has been a strong trend in the realm of consumption in recent years. Despite the growing academic attention paid to minimalistic products in the marketing field, we know little about when consumers choose or avoid minimalistic products. The first project examines how a ubiquitous consumption context—gifting—affects consumers’ preference for products with a minimalistic design. Ten studies demonstrate that consumers tend to avoid choosing products with a minimalistic design when they are intended as gifts for others. This minimalism-avoidance effect is found to be driven by consumers’ heightened motivation to (symbolically) individualize the product in the gifting context. The second project takes a different perspective, exploring a context in which minimalistic products are even more appealing to consumers. Specifically, six studies show that consumers are more interested in purchasing products with a minimalistic design when their self-control goal is made salient (vs. not salient). This effect is driven by consumers’ heightened desire to signal concentration to themselves, which is perceived as a critical fuel for achieving self-control goals. Together, these two projects offer valuable insights for marketing practitioners, helping companies strategically design and position minimalistic products to appeal to different consumer motivations.

Rising Intergenerational Transmission in School Tracking : The Mobility Consequences of College Expansion and Tuition Increase in China
This study investigates the mobility consequences of college expansion and tuition increase following a major higher education reform in China. Through a two-stage transition analysis, we find that rising college enrollments and tuition costs intensify the intergenerational transmission of education between fathers and children, by strengthening the influence of paternal education on high school tracking placement. However, the changes in enrollment and tuition have no significant impact on the educational mobility among students already admitted to the academic track of high school. Our findings suggest that school tracking is becoming increasingly pivotal in educational stratification and transmission with the expansion and marketization of higher education, and that long-run family investments in children’s education are responsive to policy changes in higher education provision.

Reality Distance: Conceptualization, Measurement, and Implications for Consumer Research
Recent technological advances, cultural trends, and sociopolitical climates have created an increasing number of alternatives to and variations of “reality,” making the concept of reality blurrier and more subjective. The present research reviews extant perspectives on reality across disciplines to provide a synthesized conceptualization of reality. Moreover, a novel construct—"reality distance”—is proposed to capture consumers’ perception that their experienced reality is outside of (vs. grounded in) objective reality. We advance two major antecedents to reality distance (i.e., experience rarity, sensory fallacy) and develop a six-item Reality Distance Scale (RDS) to measure the construct. Eleven studies using samples from different populations (N = 3,704) demonstrate the scale’s validity and reliability and situate the construct within a broader nomological network. The studies then showcase the relevance of reality distance in consumer research by documenting how the scale predicts consumer preferences and behaviors in varioius domains. We discuss the implications of the work and suggest directions for future research to unlock the theoretical and practical potential of reality distance in consumer research.

Large language model reveals the impact of digital communication on corporate taxation
随着数字经济的蓬勃发展,企业与税务机关的沟通方式正逐步向数字化转型。传统的线下和电话咨询方式存在信息记录不全、共享困难等问题,限制了纳税人获取税收政策和指导的效率。为此,税务机关推出了公开的税务留言板,提供了透明的政策咨询平台。本研究利用大型语言模型对税务留言板中的回复进行细致分类,识别出“模块化回复”和“人性化回复”。通过实证分析,我们发现人性化回复对企业营业收入具有显著的正向影响,尤其在涉及税收优惠政策时,这种影响更加明显。相较之下,模块化回复的影响相对较弱。结合公共经济学中的税收理论,我们阐释了这种影响机制。人性化回复通过降低信息不对称和交易成本,提升了企业对税收政策的理解和遵从度,促进了资源的有效配置和企业绩效的提升。我们的研究结果强调了高质量税务服务的重要性,建议税务机关提升个性化服务水平,优化税收优惠政策的宣传和辅导,利用数字技术进一步改善税务服务。

Experience-Sampling: Theory, Framing, Writing, and Reviewing
In this talk, Dr. Joel Koopman of Texas A&M University will discuss, and take questions, on a wide variety of topics related not only to his own research that uses experience-sampling (ESM), but also to excellence in research, teaching, and/or service more broadly. As a leader in the area of experience-sampling—a data collection technique frequently employed in Organizational Behavior research—Dr. Koopman has spent a considerable amount of time not only thinking on the topic and designing studies to collect high-quality, but also in responding to reviewers. This experience has given him both broad and deep insights into the methodology—insights that he loves to share with others. And even for those not using ESM in their own research, knowledge of this technique is critical for reviewing the work of others, and evaluating colleagues in your department who themselves may employ it.
Moving beyond his work in ESM, Dr. Koopman has gained a wealth of knowledge and experience in the field generally that he would love to share. As a Full Professor with an endowed position, a winner of several early-career awards and “Best Reviewer” awards, a publication record of over 40+ manuscripts in top OB/HR journals, and the Division-Chair Elect for the Human Resources Division of the Academy of Management, Dr. Koopman has thoughts, opinions, and perspectives on excellence in this profession (research, teaching, and service). In the second half of the session, he will field questions from the audience on a variety of topics and offer his thoughts to attendees.

Influencer Networks
This paper develops a model to examine the formation of influencer networks in user-generated content markets. Unlike previous research, we find that every strict equilibrium network exhibits a nested, upward-linking structure where multiple levels of influencers can coexist. Moreover, across a broad range of parameters, all payoff dominant strict equilibria conform to the law of the vital few: regardless of the population size, a small but significant group of players provides all content. We also establish a link between efficiency and equilibrium, and shows that all efficient strategy profiles are strict equilibria of an auxiliary game with larger benefit parameters. For sufficiently large populations, a single nested upward-linking network connecting all players can emerge, despite potentially polarized tastes over content categories.

Catalyst or Curse: An Analysis of Fake Engagement on Digital Content Platforms
The growing competition for visibility on digital content platforms has given rise to a shadow market for buying and selling fake social media engagement. This paper examines the economic incentives that drive content creators to purchase fake engagement and analyzes its effects on content creation, consumption, and platform policies. Using a game-theoretic model, we demonstrate how creators strategically determine content quality while deciding whether to buy fake engagement to gain a competitive edge in viewership. Interestingly, our findings indicate that, under certain conditions, fake engagement can intensify competition among creators, thereby enhancing overall content quality, increasing viewer surplus, and boosting advertising revenue for the platform. When advertising revenue-sharing is endogenously determined, platforms may have incentives to share a portion of the advertising revenue with creators to indirectly encourage the purchase of fake engagement, creating a “win-win-win” scenario for creators, viewers, and the platform. Furthermore, we find that platforms may not always have an incentive to perfect their fake engagement detection technologies, even when improvement costs are negligible.

Less is More: A General Framework of Opaque Selling
Selling opaque products has become popular on e-commerce platforms where the hidden attribute is often color or style, thanks to its obvious advantage in risk pooling the demand. This study aims to quantify the value of the flexibility that underlies opaque selling and investigate the opacity design and pricing problem. We first consider a setting
in which an online retailer sells a product with N items that only differ in a certain secondary attribute, and in addition, offers opaque options where the customer selects a subset of all products from which the seller allocates one to the customer. We find that the cost savings from using just 2-opaque products are in the same order as the fully flexible case where the opaque product contains all N items, extending the results in Elmachtoub et al. (2019). We next investigate the opacity design problem where the objective is to maximize the expected profit through opaque product design and pricing and identify conditions under which partial design outperforms a full design. Extensive numerical experiments are conducted to support our main results and insights.

ETF Loan Market: Causes and Consequences of High ETFs Lending Fees
We find that exchange-traded fund (ETF) lending fees are significantly higher than individual stocks. Although the create-to-lend (CTL) mechanism helps alleviate supply constraints when borrowing demand rises, its effectiveness is hampered by various costs and frictions, including the lack of competition among authorized participants (APs), hedging challenges inherent to the CTL process, and the costs and frictions associated with creating ETFs. These limitations contribute to elevated ETF lending fees (i.e., outside lending) and notably impact the stock lending market (i.e., inside lending). Specifically, increased short selling through cheaper-to-borrow ETFs can exert downward pressure on stock lending fees. Our findings highlight the constraints on arbitrage opportunities within ETF markets.

Outside the LCR Box:The Impact of Liquidity Regulation on Banks
This study investigates the far-reaching effects of liquidity regulation policies on the banking sector in China. Banks subject to liquidity coverage ratio (LCR) regulation since 2014 are found to have significantly decreased their short-term wholesale funding via interbank liabilities while increasing other short-term funding via bonds to pay (primarily interbank negotiable certificates of deposits) on the liability side. The finding of this research that is the most different from other studies is that regulated banks in China neither significantly increased their holdings of qualified high-quality liquid assets, nor significantly reduced their proportion of risky assets, after the implementation of LCR regulation. Under the pressure of deposit price control and a competitive deposit environment, banks with greater market power have attracted more traditional deposits than banks with lower market power, and banks with fewer local market shares have shifted to increase their proportions of other liabilities to satisfy the liquidity requirements. This has ultimately led to unexpected consequences in China’s banking industry.
